Keep your BlackBerry Niagra/ Tour horizontally aligned on your belt for easy accessibility with the BlackBerry Horizontal Holster. It features a leather-wrapped metal clip to attach onto a belt, waistband, or briefcase. Grooves run along the inside of the case to protect the trackball. Plus, a magnetic proximity sensor determines if your BlackBerry Niagra/ Tour is in its case and shuts off the screen to conserve battery life, while giving you the option to choose unique notification settings for incoming calls and other functions.
